VAPOR FEED FOR GASOLINE LANTERNS.

Application filed October 12, 1922. Serial No. 593,940.

To all whom it may concern Be it known that I, RICHARD T. GRADY, a citizen of the United States, and resident of San Diego, county of San Diego, and State of California, have invented a certain new and useful Improvement in Vapor Feed for Gasoline Lanterns, of which the following is a specification.

My invention relates to that class of lanterns having the burner located above the font or gasoline container. It is well known to persons skilled in the art that there is always a quantity of inflammable vapor present in the space intermediate the top of the gasoline and the top of the font or container.

My invention has for its object to utilize this vapor for furnishing the initial fuel to the burners until the burner shall become sufficiently heated to generate the gas from the gasoline itself. In this way I am able to do away with the annoyance of having to heat the generator or feed pipe with a blow torch or other heating means, besides avoidin the delay incident upon that process. I

y means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which-- Fig. 1 is a side elevation partially in section showing my improvement applied to a gasoline lantern of the type described, the chimney being omitted for the sake of clearness.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings the device comprises a font or gasoline container 21 which is provided with a pump 22 mounted in the font itself for the purpose of supplying pressure on the gasoline.

A feed pipe 23 leads from a valve 24 to a mixing chamber25 where the gas is mixed with air which is conveyed to the mixing chamber through an air pipe 26 whenceit is conveyed to the mantles 27 and 28 through branch ipes or arms 29 and 30. A pipe 33 opens into the space 31 intermediate the top of the gasoline 32 and the font 21. A pipe 33 leads to a valve 34 from which another pipe 35 leads to the generator of feed pipe 23 adjacent the mixing chamber 25. A stuffvapor in the space 31 to flow through the pipes 33 and 35 into the feed pipe 23 whence t passes into the mixing chamber 25, where it is mixed with the air entering through the air pipe 26 and passes through the arms 29 and 30 to the mantles 27 and 28 where it can be ignited by a match or any other similar means for lighting it.

Practice has shown'that there is always sufficient vapor in the space 31 to furnish light, until the heat generated by the flame at the mantles 27 and 28 is sufliciently great to generate gas from the gasoline itself when the needle valve 3 1 can be closed and the gasoline will travel through the feed pipe 23 into the mixing chamber as heretofore described. It will thus be seen that in this way I entirely avoid any necessity for ex terior means of heating the generator or feed pipe for the lantern, as well as doing away with the delay caused by the lapse of time required to heat the'feed pipe.

Although I have shown and described this specific embodiment of my invention, I do not wish to be understood as limiting myself to the details of construction therein shown and described, as they are merely for the purpose of illustrating a preferred concrete embodiment of my invention and many changes in construction may be made therein without departing from the scope of my invention, and I do not desire to be understood as limiting myself in any way except in so far as limitations may appear in the hereinafter appended claims.

Having described my invention what I regard as new and desire to secure by Letters Patent is 1. In a gasolin lantern having a font, a feed pipe, leading from the font to a burner above and connected to said feed pipe, an air pipe leading to said burner, mantles on said mixin chamberarms leadin from the mixabove the font, there being a mixing chamber in said burner, a feed pipe connecting the said mixing chamber to the font, a Valve in said feed pipe, an air pipe leading to the per part of the font to the inside of the feed pipe at a point adjacent the mixing chamher, and a valve in said tube. 10

In testimony whereof I have signed the foregoing; specification. ing chamber, mantles at the extremities of said arms, a tube which leads from the up- RICHARD T. GRADY.
